Abstract:
Uvaia is a Brazilian native species whose fruit has few studies on the nutritional composition and antioxidant properties. In this study, we evaluated for the first time the proximate composition, mineral content, carbohydrate profile, identification of organic compounds, and determination of antioxidant properties in two fractions of this fruit (edible fraction and seed). Edible fraction showed the highest content of ash, lipids, proteins, total fibers, minerals mainly K and Mg (1557.61 and 124.40 mg 100 g-1, respectively), and carbohydrates such as fructose, sucrose, glucose (123.08; 64.40; and 42.39 mg g-1, respectively), and maltotetraose (G4). From the ESI-LTQ-XL-MS/MS analysis, it was possible to identify 22 compounds in the edible fraction and 16 compounds in the uvaia seed, including organic acids, phenolic acids and flavonoids. On the other hand, uvaia seed had the highest content of total phenolics, flavonoids and antioxidant capacity. These results suggest that this fruit has great potential to be used in industry, with emphasis on making food with functional claims.
